Very first tutorial lesson does not work due to ZLIB

[Nady93]

Tutorial from tutorial\consuming_packages\simple_cmake_project\ does not build with commands provided from first lesson in documentation I am trying to follow (https://docs.conan.io/2/tutorial/consuming_packages/build_simple_cmake_project.html)

When I do conan install . --output-folder=build --build=missing, it finishes with "finished successfully" status, despite of two warnings
WARN: deprecated: Usage of deprecated Conan 1.X features that will be removed in Conan 2.X: WARN: deprecated: 'cpp_info.names' used in: zlib/1.2.11
However next command which is cmake .. -G "Visual Studio 15 2017" -DCMAKE_TOOLCHAIN_FILE="conan_toolchain.cmake" fails with
CMake Error at C:/Program Files/CMake/share/cmake-3.28/Modules/FindPackageHandleStandardArgs.cmake:230 (message): Could NOT find ZLIB (missing: ZLIB_LIBRARY ZLIB_INCLUDE_DIR)

I have changed required ZLIB version to 1.3.1 and now it works.

Hi @Nady93

Thanks for your report.

Can you please post the full output of conan install command? Is VS 15-2017 the one you have installed and want to use?

[Nady93]

It is worth to mention, I have skipped specifying cmake generator, therefore it were using VS 2022 (only one I have installed)

Full output from conan install.

I am a bit confused, I honestly don't know what could be failing.

Could you please do the following too?

• Double check that no files from the example were changed (git diff)
• Post the full cmake ... command that you are using and the full output of that command.
• The cmake error that you are sharing shows it is 3.28, but if you can also share the full cmake --version number, and I guess it was a pretty standard cmake installation? Or does your cmake have something special?
